I don't know as much about computers anymore as I used to, but I'm looking to upgrade a desktop system I've got running with an ASUS P5K VM Mobo & Core 2 Duo 6300. It currently has 1GB of ram in it, and I'd like to up it to 2GB. I'm trying to decide between 667mhz ddr2 or 800mhz ddr2. As I recall the efficiency depends on your CPU bus speed or something of the such, but I really don't know.
Specifically I'm deciding between these two rams:

I'm on a budget, so should I pay the extra for 800mhz ram, or just go with the basic 667mhz value ram?
